Be it known that I, WALTER I. MURBHY, a citizen of the'United States, residing at New York in the county of New Yorkand State of ew. York, have invented certain new and useful 'Improvements in Corruated'Sheet-Metal Car Ends, of which the ollowing isa specification. u

My invention relates to a sheet metal end structure for :railway cars, more particularly for box cars, and the primary object of the invention is to provide a ycar end structure composed of one or more metal sheets, preferably of a plurality of. sheets, overlapped and secured together, said sheet or sheets formed with vertically disposed strengthening and rigidifying corrugations or projections so diSPOSBd as to afford a maximum reinforcement midway between vthe side walls of the car.

In a vertically corrugated sheet metal car end the corrugations serve as bea-ms to transmit any cargothrust to the car framing, and also, to a certain extent, as posts to carry the roof load. Both stresses are likely to be greatest near the vertical center line of the end. The rtions of the end structure adjacent the side walls of the car are rigidified and strengthened by the corner posts and therefore do not require the reinforcement provided by the corrugations to the extent, at least, that the middle portion requires such reinforcement. In vaccordance with my present invention the middle portioniof the end is formed with corrugations or ribs of maximum depth while the side portions of the structure are provided with corrugations of lesser depth. In order to facilitate the fabrication of the end structure it is made up of a plurality of sheets, each sheet having corrugations of the same depth but the corrugations of the middle sheet being deeper than those of the sheets on opposite sides thereof.

A further object is to provide a sheet metal end structure composed of a vertically corrugated end sheet or sheetsoccupying the middle portion of the end and flat metal sheets at the extreme sides of th-e end structure.

The invention consists 'of the new and improved constructions, arrangements and devices shown in the drawing hereto 'attached and to be hereinafter described and claimed for carrying ont the above stated objects and such other incidental objects as will be hereinafter referred t0.

A'prefelrred embodiment ofthe invention is shown in thedra-wing in whehi Figure 1 is an end view of 4`the super- Structure 0f a'ratilway box .Car provided with a sheet metal end eonstruoted'in accordance with my invention. n

The end structure is composed, in this embodiment of the invention, 'of seven sheets or strips of metal designated 15, 16, 16, 17, 17 and 18, 18 which are overlapped on vertical lines and joined together by means of rivets 19,. The low-,er edges of 'the sheets are inturned to provide flanges 20 which are secured to the end sill by bolts 21 or other suitable fastening devices. In'this preferred -forno ofthe invention the sheets 18, 18 at the sides of the end structure are fiat, that 1s to say, are not corrugated and are formed on the outer vertical edges with flanges 22 secured to ,the corner4 postsv 11 by bolts 23. The sheets 17, 17 are formed with vertically disposed .corrugations 24 which are relatively shallow. The plates 16, 16 are `formed with deeper'` corrugations 25 and the center plate 15 is formed with still deeper corrugations 26. The corrugations of each sheet are of the same cross sectional configuration.

The upper edges of the sheets are preferably bent over inwardly on lines corresponding to the slope of the car roof to provide anges'27, 28, 28, 2929 and 30, 30, these flanges being secured together by rivets 31 to constitute a rigid member or structure which widens toward the side walls of the car Jfor supporting the ridge pole 13 and purlins l and for giving rigidity to the upper portion of the -end Wall panel, this flange structure, inlefl'ect, taking the place of the usual end plate of the car. T heflanges 30 are secured to the side plates 12 by means of angle brackets 32.
